Truck Camper Cover needed, Recommendations?

I've gone through several of the Classic Accessories type of cover, in the California sun by 18 months they are looking pretty sorry and by 24 month, pieces. The Calmark cover is still looking quite good at 4 years. Just beginning to abrade a the pointy bits (they supply material to reinforce these once recognized, which I haven't done). The downside is the cost, and also they are heavy compared to the lightweight disposable ones, and harder to get on and off as a result.
